AI Technical Summary

Technical Problem

Current endoscopic ultrasound balloons cannot be angled at bends in the digestive tract, cannot fit tightly, reduce the sealing effect, and are inconvenient to assemble, affecting examination efficiency and stability.

Method used

A balloon structure was designed, comprising a main tube, a secondary tube, a hollow gooseneck tube, an adjustment ring, and a connecting mechanism. The angle adjustment and sealing are ensured through the cooperation of the adjustment ring and the guide block, and rapid assembly is achieved by using the connecting sleeve and the positioning buckle.

Benefits of technology

It enables adjustment of the capsule angle according to the bend angle of the digestive tract, improving the sealing and stability of the occlusion, simplifying the assembly process, and improving the convenience and efficiency of the examination.

Abstract

The balloon structure comprises a main catheter and a one-way valve arranged on one side of the main catheter, an auxiliary catheter is arranged on one side of the main catheter, the auxiliary catheter is detachably connected with the main catheter through a connecting mechanism, a hollow gooseneck pipe is arranged on one side of the auxiliary catheter, and the hollow gooseneck pipe is detachably connected with the main catheter through a connecting mechanism. A bag body structure is arranged on one side of the auxiliary catheter; the bag body structure comprises a hollow bag body, the bottom face of the hollow bag body is arranged on the outer surface of the auxiliary catheter, multiple sets of water inlet pipes are further arranged on one side of the auxiliary catheter and communicated with the hollow bag body, and an adjusting ring is further arranged on one side of the hollow bag body and slidably arranged on the auxiliary catheter. The angle of the hollow bag body can be adjusted according to the bending angle of the digestive tract, the hollow bag body can be conveniently guided in, meanwhile, expansion of the hollow bag body is guided, the sealing performance of the hollow bag body on plugging of the digestive tract is improved, overall installation and operation are convenient, and medical staff can conveniently use the hollow bag body.
